PIPE AND GAS CONNECTION.

Application filed May 21.

To all whom it may concern:

-Be it known that I, HERMAN E. LOEBE, a citizen of the United States, and a resident of in the county of Hudson and State of New Jersey, have invented a new and useful Im )rovement in Pipe and Gas Connections, 0' which the following is a full, clear, and. exact description.

The purpose of the invention is to provide a connection between a gas sup ly pipe and a gas stove or the like, capable of eing quickly and conveniently made and in a thoroughly gas-tight manner, without the em loyment of the customary flexible rubber .tu e, and also to rovide a coupling that can be as readily and conveniently disconnected as applied.

' It is a further purpose of the invention to provide a coupling or connection of the character described, that will be rigid and nonleakable at either'end, and which in its construction will be simple, durable, economic and capable of ready manipulation.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures. I

Figure 1 is a side elevation of the coupling, illustrating its application to a gas range; Fig. 2 is a sectional side elevation of the coupling, drawn upon an enlarged scale; and Fig. 3 is a section through the lower portion of the connection or coupling, illustrating the operating leverof that part in vertical position.

A represents a gas cook that is secured to the gas sup ly or service pipe 10, and the said cock A 1s provided at its outlet end with the customary thread 11, and likewise with an interior conical chamber 12. The connecting pipe B employed is of metal, and is provider at its inlet end with a conicalhead 13, that is made to fit snugly in the conical chamber 12 of the gas cock A, and the said head 13 is provided with an annular flange 14 whereby to'hold in position thereon a nut ted to be screwed upon the exteriorly threa ed portion 11 of the gas cook, so as to draw the head 13 in the chamber of the latter and make a thoroughly gastight connection.

At the lower end of the connecting pipe B, which pipe may be given any desired shape,

tion of the said lever D,

Patented Jan. 28, 1908.

an outlet head 16 is provided and this outlet head 16 is also conical or oftapering shape, but its rear portion is reduced in diameter so as to provide an annular shoulder 17. This outlet head 16 is adapted to enter a correspondingly tapered chamber 18 in a fitting O, which fitting is screwed to or is otherwise connected with the supply pipe 19of a gas range (1, a gas stove or the l1ke. The said fitting C is provided at its upper central portion with a segmental lug 20, and the fitting C is furtherprovided with an operating lever D, the lower portion 21 so as to straddlethe fitting C, and the upper portion 23 of the said lever is tubular and its upper end is covered by a cap 24. A detent 25 is located within the upper tubular secand this detent is pressed downward by a spring 26, engaging with the upper end of the detent, the spring being located within the tubular section of the lever D just below its cap 24.

The side members of the bifurcated sec tion 21 of the operating lever D extend down belowthe fitting C, and the said members are pivotally connected with the said fitting by screws 22 or their equivalents. The detent 25 is provided at its lower end with a groove 27, so that the said detent can straddle and yet engage with the lug 20, as is 3, in which figure the lever shown in Fig. 7 D IS in a vertical positlon. Links 28 are pivoted to the lower ends of the side members of' the lower section of the said lever D, and the said links are also pivoted to a slotted collar 29, which collar is adapted to slide upon the outlet head 16 of the connecting pipe B, and when the said head 16 is forced intothe fitting C the said collar engages with the shoulder 17 on the head 16, as is shown in Fig. 2, firmly holding the head 16 in the said fitting and in such manner that there can be no possibility of leakage. The detent 25 carried by the lever D acts to prevent the said lever from being accidentally moved from its set position.

In the operation of the device, the pipe B having been connected in the manner described with the source of gas supply, the outlet head 16 is entered into the chamber 18 of the fitting C, the lever D being then carried in direction of the outlet end of the said fitting, so as to leave the collar 29 free to be moved up or down from the head 16 of the connecting pipe B. The collar 29 is then brought to a lower position straddling the whereof is bifurcated pipe B, and the lever D is-carried to the claim as new and desire to secure by Letters outer position shown in Figs. -1 and 2, Patent,

thus drawing thecollar 29 firmly against the The combination with the pipe, provided shoulder'17 of the entering head 16,iorcing with a conical outlet head, and an annular 1 the said head into close engagement with the shoulder at the junction of the head with the 30 wall of the chamber 18 in the fitting'and pipe, of a fitting provided with a conical holding it in such position. Thus it will be opening for receivingthe head, a tubular observed that a connection between the operating lever having its lower portion source of gas supply anda stove, for example, bifurcated to straddle the fitting and pivoted 10 can be quickly made by one movement of thereto, a slotted collar engaging the anthe lever D, and the disconnection can beas nular shoulder, links connecting the collar quickly accomplished by a sin l e movement with the operating lever, and a detent slidof the lever D in an opposite irection. able in the tubular portion of the lever, said I desire it to be understood that while I fitting being provided with a segmental lug 15 have described the device as especially for engagement by the detent, whereby to 40 adapted for use in makin g'as connections, retain the operating lever in its adjusted poit can be used with equafiy good results in sition, said detent being grooved to permit it making water connections; in fact, the deto straddle the lug.- ice'is practically a coupling for making pipe In testimony whereof I have signed my 2 connections. It is also evident that by name to this specification in the presence of screwing down the cap 24, the lever D may two subscribing witnesses; be held more or less rigid, and that in con- HERMAN E. LOEBE. necting pipeswith my device, no tools are Witnesses: necessary. GUSTAV A. MISTERFELD,
